Android 自定義TextView控件，用來組成表格方便數據的展現。android

首先看一下效果canvas

樣式不是很好看，須要用的能夠本身優化一下。app

實現方式很簡單。ide

　　一、自定義控件 MyTableTextView 繼承 TextView 重寫onDraw方法。在裏面添加話邊框的操做。佈局

 1 package lyf.com.mytableview;
 2 
 3 import android.content.Context;
 4 import android.graphics.Canvas;
 5 import android.graphics.Color;
 6 import android.graphics.Paint;
 7 import android.util.AttributeSet;
 8 import android.widget.TextView;
 9 
10 /**
11  * lyf on 2016/06/27
12  * 自定義TextView
13  */
14 public class MyTableTextView extends TextView {
15 
16     Paint paint = new Paint();
17 
18     public MyTableTextView(Context context, AttributeSet attrs) {
19         super(context, attrs);
20         int color = Color.parseColor("#80b9f2");
21         // 爲邊框設置顏色
22         paint.setColor(color);
23     }
24 
25     @Override
26     protected void onDraw(Canvas canvas) {
27         super.onDraw(canvas);
28         // 畫TextView的4個邊
29         canvas.drawLine(0, 0, this.getWidth() - 1, 0, paint);
30         canvas.drawLine(0, 0, 0, this.getHeight() - 1, paint);
31         canvas.drawLine(this.getWidth() - 1, 0, this.getWidth() - 1, this.getHeight() - 1, paint);
32         canvas.drawLine(0, this.getHeight() - 1, this.getWidth() - 1, this.getHeight() - 1, paint);
33     }
34 }

View Code

　　二、主佈局，什麼也不用寫。直接放一個LinearLayout就好。但由於表格的寬度和高度每每超過屏幕的寬高度，所以須要咱們添加ScrollView 和HorizontalScrollView。爲了讓HorizontalScrollView填滿整個ScrollView 須要在ScrollView設置屬性 android:fillViewport="true"。優化

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true"
        android:scrollbars="none"
        >

        <HorizontalScrollView
            android:id="@+id/scroll_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scrollbarAlwaysDrawHorizontalTrack="false"
            android:scrollbars="none">

            <LinearLayout
                android:id="@+id/MyTable"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:layout_marginBottom="9dp"
                android:orientation="vertical"
                >
            </LinearLayout>

        </HorizontalScrollView>
    </ScrollView>
</LinearLayout>

View Code

　　三、接下來寫表格顯示的樣式文件table.xml。該佈局文件用來顯示錶格每一行的樣式。this

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="match_parent">

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_1"
        android:layout_width="50dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_2"
        android:layout_alignTop="@+id/list_1_2"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_2"
        android:layout_width="180dp"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/list_1_1"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_3"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_2"
        android:layout_alignTop="@+id/list_1_2"
        android:layout_toRightOf="@+id/list_1_2"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_4"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_3"
        android:layout_alignTop="@+id/list_1_3"
        android:layout_toRightOf="@+id/list_1_3"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_5"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_4"
        android:layout_alignTop="@+id/list_1_4"
        android:layout_toRightOf="@+id/list_1_4"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />

    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_6"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_5"
        android:layout_alignTop="@+id/list_1_5"
        android:layout_toRightOf="@+id/list_1_5"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />


    <lyf.com.mytableview.MyTableTextView
        android:id="@+id/list_1_7"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/list_1_6"
        android:layout_alignTop="@+id/list_1_6"
        android:layout_toRightOf="@+id/list_1_6"
        android:gravity="center"
        android:textColor="#000"
        android:textSize="13sp" />
</RelativeLayout>

　　四、最後把數據放到咱們的table.xml文件中，並顯示到咱們的主佈局文件中。spa

package lyf.com.mytableview;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;

/**
 * lyf on 2016/06/27
 * 自定義表格顯示
 */

public class MainActivity extends Activity {

    private LinearLayout mainLinerLayout;
    private RelativeLayout relativeLayout;
    private String[] name={"序號","考號","姓名","出生年月","語文","數學","英語"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mainLinerLayout = (LinearLayout) this.findViewById(R.id.MyTable);
        initData();
    }

    //綁定數據
    private void initData() {
        //初始化標題
        relativeLayout = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.table, null);
        MyTableTextView title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_1);
        title.setText(name[0]);
        title.setTextColor(Color.BLUE);

        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_2);
        title.setText(name[1]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_3);
        title.setText(name[2]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_4);
        title.setText(name[3]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_5);
        title.setText(name[4]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_6);
        title.setText(name[5]);
        title.setTextColor(Color.BLUE);
        title = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_7);
        title.setText(name[6]);
        title.setTextColor(Color.BLUE);
        mainLinerLayout.addView(relativeLayout);

        //初始化內容
        int number = 1;
        for (int i=0;i<10;i++) {
            relativeLayout = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.table, null);
            MyTableTextView txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_1);
            txt.setText(String.valueOf(number));

            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_2);
            txt.setText("320321**********35");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_3);
            txt.setText("張三");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_4);
            txt.setText("1992/04/21");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_5);
            txt.setText("150");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_6);
            txt.setText("200");
            txt = (MyTableTextView) relativeLayout.findViewById(R.id.list_1_7);
            txt.setText("120");
            mainLinerLayout.addView(relativeLayout);
            number++;
        }
    }
}
